Mass Spectrometry Facility

The mass spectrometry facility is housed in a 1000 sq ft laboratory located in the UMSL Research Building (R003), and also in R-103 where the Bruker Maxi Plus is located. In addition to the mass spectrometers described below, there are areas for data processing, instrument maintenance, parts storage and sample preparation.  The instrumentation is used primarily for support of research and teaching in the Department of Chemistry and Biochemistry, however in years past the MS facility has been a resource for the local business or members of the academic community which lack this instrumentation.

Mass Spec Form


 Maxis plus ms in bythell lab

 Bruker Maxis Plus (maXis HD) quadrupole time-of-flight mass spectrometer and UHPLC.  It comes with Electrospray ionization, atmospheric pressure photoionization and a solids probe for ionizing solids directly. It can do m/delta m = 60,000 and collect up to 20 spectra per sec.

 

 New MS

 The department’s most recent MS instrumental acquisition is an Agilent 6220 Accurate-Mass Time-of-Flight (TOF) LC/MS system, which provides both high sensitivity and mass accuracy sufficient to identify molecules. Ionization via either electrospray or atmospheric pressure ionization makes the system especially versatile and MassHunter software supports both qualitative and quantitative analysis. 
 

 HP 6890 GCMS


HP 6890 GC with Agilent 5973 Mass Selective Detector.

For routine mass spectral analysis following capillary column gas chromatography (GC) separation with:

  • Electron impact (EI) and chemical ionization (CI) capabilities.  Set up for the latter is pending
  • Work stations for data processing and library spectral searching.
